Special Characters In Filenames

[tomsam]

 

Hi all,

 

recently, I tried to sync a file with a name similar to the following 

 

Screenshot - 02022014 - 10:32:03 AM.png

 

from a Ubuntu 12.04 system (running btsync 1.2.82) to a Windows 7 Pro system (running btsync 1.2.82). The sync didn't start. I googled a little bit, and some users were talking about problems with special chars. Thus, I renamed the file to  "Screenshot_02022014_10_32_03_AM.png" and the sync started and completed.

 

Can anyone enlighten me a little bit on  what the term "special chars" in this case is supposed to mean? Is there a list of characters that cannot be used? Does this depend on the target system (to be precise on the target file system, e.g. NTFS does not accept "/\*?<>|: in filenames, if I remember well)? 

 

In other words: What happens, if there is a filename with an illegal filename on the target system? Is there any kind of transformation applied to the filename, or are the files just stuck forever?

 

In addition, I want to use btsync to synchronize my dad's "Own files" folders to a System R running a unix environment (PC->R only via an RO-secret, target filesystem ext2,ext3 or ext4). Will it be likely that I'll be getting problems with special characters (like Umlauts äöüß) in filenames that my father used on his Windows 7 system?

 

Regards,

tomsam

 

PS R could be a NAS or  simply a USB drive attached to a Pi.
